From: Samoline1 Linke on 1 Feb 2010 04:24 Is it possible that I highlight the first and last point of the scatter plot? This would help me in checking from which point my scattter plot starts and where does it end.

If you have two vectors x and y of size n Then you could do scatter(x(1),y(1),'r') hold on scatter(x(2:n-1),y(2:n-1),'b') hold on scatter(x(n),y(n),'r') First and last points will be in red while the others will be in blue.

Actually I have a big matrix having 20 columns. I want to make scatter plots of these columns against each other. I have found that 'gplotmatrix' is one of the best solutions representing scatter plots of so many vectors. Is it possible that I could include the commands you told me into gplotmatrix? so that I could get highlighted start and end points in scatter plots made through gplot`? I shall be highly thankful for your help!

I don't have the "statistics toolbox" so I don't have the "gplotmatrix" command but I guess that you should be able to use "gplotmatrix"command in the same way as I have used the "scatter" command. Good luck !
